ICOPE-15-1049 Progress Update of MHI Air Blown IGCC and Oxygen Blown Gasification Plant

抄録

From the viewpoint of energy security and global warming issues, highly efficient coal utilization system, such as the integrated coal gasification combined cycle (IGCC) power systems and chemical synthesis processes using coal gasification are increasing their market size. As one of the leading companies in the field of IGCC and coal gasification, Mitsubishi Hitachi Power Systems, Ltd. (MHPS) which jointly established by Mitsubishi Heavy Industries, Ltd. (MHI) and Hitachi, Ltd., and MHI are now in a position to build up market share. With an integration of two-stage entrained flow air-blown coal gasifier, the IGCC will achieve the highest net plant efficiency by using air as the gasification agent, and the F or G-class high temperature combustion turbine for power generation market. This paper includes discussions on the latest status of the 250MW Nakoso IGCC commercial plant and overview of 500 MW class plant integrated with the F or G-class high temperature gas turbine. This paper will also discuss about our latest activities on the oxygen-blown gasification systems for chemical synthesis and application to biomass and petroleum coke.
